ROD-COILING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 444,653, dated January 13, 1891. Application led October 6,1890. Serial No. 367,190. (No model.)

To @ZZ whom t may concern:

Be it known that I, HENRY ROBERTS, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Rod-Ceiling Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional side elevation showing my improved coiling apparatus, together with means for carrying away the coiled rods. Fig. 2 is a plan view thereof. Fig. 3 is a vertical cross-section, on an enlarged scale, on the line III III of Eig. 1. Fig. 4 is a side elevation of the coiler, partly in vertical section. Fig. 5 is an enlarged cross-sectional view on the line V V of Fig. 4 Fig. 6 is a view similar to Fig. 4, showing a useful attachment to the coiler to prevent the wear ordinarily occasioned by the rod. Fig. '7 is an enlarged cross-section on the line VII VII of Fig. 6.

Like symbols of reference indicate like parts in each,

In rod-mill practice in which the finished rod is received from the rolls by a rotating coiler and delivered in a coil the removal of the hot coils has been attended with considerable labor and expense.

One object of my invention is to save this, and thus to lessen the cost of manufacture of the rods.

The second object of the invention is to prevent Wear on the end of the coiler and to provide means by which the last end of the rod can be wrapped with greater certainty around a drum or spool which serves to draw it from the coiler.

Referring to the figures on Sheet 1 of the drawings, 2 2 represents a series of rotating coilers, which may be constructed as shown in my prior patent, No. l436,067, dated April 22, 1890, and each of which is adapted to receive the rod from the rolls and by rotation to deliver it in a coil upon a receiving table or floor. I shall describe their construction more in detail hereinafter with reference to the iigures on the second sheet of the drawings. Near the coiler is a covered way 3, which leads to the place in the mill where it is desired to receive the coils for use or for preparation for shipment. The surface of this way is preferably formed with parallel ribs l, and may incline upwardly to a downwardly-inclined chute 4t.

5 6 are sprocket-Wheels journaled in the way 3, one of them being provided with suitable driving-gear 7.

8 is a sprocket-chain extending around these wheels in a vertical plane and provided at intervals with outwardly-projecting rods or spurs 10, which are iiXed to the chain-links, as shown in Fig. 3, and which in the upper branch of the chain pass through a slot in the cover of the way 3. At or above this slot is a track composed of upright parallel rails or flanges 15, and the spurs are made of sufficient length to extend above the same.

9 9 are rollers by which the upper branch of the chain is supported.

In using the apparatus the operator, who stands at the coiler or coilers, takes the rodcoil with a hook` or other instrument and places it on the rails 15 over one of the passing spurs 10; or the saine end may be attained by placing it just over the rear of the sprocketwheel 5, so that the nextspur in rising through the slot will enter the coil. The coil, then resting in an inclined position on the rails and on the ribs 1, is pulled along the same until it reaches the chute 4, where, being released from the spur by the downward passage of the latter over the sprocket-wheel 6, it descends the chute to the mill-floor.

A material advantage is gained by the use of the rails 15, since the coil is supported thereby in an inclined position and is carried by the spur without such disarranging or tangling as would be apt to occur were the coil dragged on its sides along a flatsurface.

The great saving of labor and the facility of operation afforded by my improved conveying device will be appreciated by those skilled in the art and familiar with the difficult labor heretofore required to remove the coils from the sub floor or cellar in which they are deposited by the coiler. The length of the sprocket-chain may be as great as desired, and the coils therefore may be carried to any convenient part of the rod-mill.

I shall now describe the construction of my improved coiler-,which is illustrated in detail IOO in Figs. l-, 5, (i, and 7. lhe eoiler may consist of two concentric cones t1 c, connected by an intervening rib or ribs Il, the outer conc bcing open at the top,so that it may receive thc rod as it is delivered from the rolls. The coiler is supported in a suitable housing, (not shown,) and is rotated on its vertical axis by proper gearing. rllhe rod is delivered from the rolls to and through the space between the cones, through which it travels in contact with the rib Il, and is distributed in a coil upon a lloor or platform I2. In order that the last end of the rod may be delivered from the cone when the rod has lost its propulsive power by having` passed through the rolls, I employ a drum 13, which is adapted to be raised within the circle described by the delivery end of the coiler. So long as the rod is propelled by the rolls it is distributed in a loose coil; but when it has passed the rolls the rotation of the coller wraps it around the d ruin,and such wrapping by exerting tension on the rod draws its end from the coiler. If in order to effect this result the drum were raised within the limits of rotation of the coiler proper, although this could be done, difficulty would be experienced in causing the drum to enter the cone without making it of unduly small diameter, and if the drum should not enter well within the limits of the coiler there would be a space in which the rod would be apt to be snarled. To preventthis I employ a lip or projection Il, which extends down from the rib ll below the base of the cone for a considerable distance. After passing below the cone the rod is guided by contact with this projection, and it' the drum be raised so as to be well within the limits of the circle described by rotation of the projection the wrapping of the rod and drawing out of its last end will be eliected without difficulty. As this projection is apt to wear by friction of the rod, I may make it of a separate piece, which is detachably set in position, as shown in Figs. 4: and 5, and when worn can be rcmoved and replaced by another. This is ol advantage even when the lip does not extend below the end of the coiler, since the wear at the delivery end of present coilers, which rapidly spoils their utility, can be prevented by inserting a removable piece against which the passing rod has a bearing. In order, howover, to prevent wear of the parts as much as possible, I prefer to employ an anti-friction roller 10, Figs. G and 7, which is journaled at the rib at the lower end ofthe coiler. The rod passes in contact with this roller, which reduces the friction, and thus saves largely the abrasion which otherwise occurs with considerable rapidity. The removable wearin g-piece or the anti-friction roller lnaybe applied with beneiit to tubular coilers or rotating-'coilers of various patterns.

lVithout limiting myself strictly to the described forin ot the coiler, which may be varied in divers ways within the scope of my invention, I claim-- l. In rodcoilingapparatus,thecombination, with a rotatory ceiling-cone having a downwardly-extending distributing-rib. of a lip set removably in a recess at the end of said rib and projectingr below the same, and a drum which is vertically movable within the limit of rotation ot the lip to cause removal of the last end of the rod, substantially as and for the purposes described.

2. In a rod-coiler, the combination, with a rotatory coilin g-chan nel through which the rod passes and by which it is delivered in a coil, oi a roller situate at the delivery end of the channel, substantially as and for the purposes described.

3. In apparatus for conveying coiled rods from a rod-coiler, the combination of a track or way, adjacent elevated rails 15, on which the coils may ride in an inclined position, said rails having an intermediate slot, and an endless chain having spurs projecting between the rails, substantially as and for the purposes described.

4t. In apparatus for conveying coiled rods from a rod-eoiler, the combination of a tra-ck or way on which the coils may ride, an endless connecting-chain having spurs for engaging and conveying the coils, driving-wheels for the chain, and a downwardly-inclined chute at the final driving-wheel, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 3d day of October, A. D. 1890.
